The love for the Pacific Northwest is amplified by the amazing tree scapes found within the region – not to mention easy access to the coast in one direction and the mountains in another… drive a bit further and you can even experience the desert.
Of course, though, my first and foremost attachment to this area are the amazing and diversified trees.
It saddens me when a beautiful and seemingly healthy tree is toppled by mother nature – and, it always seems to be the glorious older trees affected the most. The “WHAT IF” thoughts start racing through my mind when the news coverage highlights tree damage from a strong storm.
What if… the tree had been regularly maintained. What if… the tree was given ample room to grow. The questions could go on. Seriously, though, there is a tremendous emphasis here on the importance of regular maintenance for a tree, especially urban trees. While many skip the thought of spending money to prune a tree, they forget (or maybe are not educated) about the impact improper pruning techniques can have on the structural integrity of a tree.
Think for a moment about a tree that may be growing next to a home. It is 30 feet to the top and it’s span is vast. Imagine the tree has been there for quite a few years and a homeowner decides it’s time to prune some of the branches away from the home – giving it some “building clearance”, as an Arborist would say. The way I see it, the homeowner has a couple options – hire an Arborist or Do It Yourself. Now, I’m not gonna lie, if I were the homeowner and this were a smaller, juvenille tree that needed a few snippets here and there – I myself might conquer the task on my own. However, the daunting task of conquering a 30-foot tree on one’s own is just asking for trouble.
The trouble starts with the huge risk of personal injury – let’s face it, most homeowners lost the “daredevil” attitude years ago. Adding to the layers of trouble, there is the major issue with the age of the tree as the technique to prune a mature tree is much different than that of younger trees. Plus, do you realize how much one of those “branches” actually weigh?!? Don’t be deceived, they are several hundred pounds heavier than your lowest guess.
Getting back to the initial scenario of building clearance. Let’s continue the story that the homeowner decided to tackle this project on his own. Since the tree provides beautiful curb appeal for the front of the home, the homeowner elects to just remove the branches extending toward the home and viola, building clearance.
The improper pruning in the formula is based on the fact that the pruning completed by the homeowner actually created a hazardous situation for the tree. By making such vigorous cutting/pruning on just one side of the tree (side next to home), it created an unbalanced structure within the tree – essentially the weight of the limbs/branches is not distributed evenly and is thus causes increased stress on the side gone un-pruned.
This situation places the tree in tremendous danger – the right mix of saturated grounds from winter or spring storms along with high wind gusts or sustained winds will cause this tree to fall over.
